Solution

1. Preparation

Gather necessary tools and parts.
Ensure the work area is clean and well-lit.
Disconnect the battery before performing any repairs.

2. Battery Inspection and Replacement

Check Battery Voltage:
- Use a multimeter to measure the battery voltage; it should be above 12.4 volts.
Clean Battery Terminals:
- Remove any corrosion from the battery terminals with a wire brush.
Replace Battery if Faulty:
- If the voltage is low or the battery is old (>3 years), replace it with a new one of the same specifications.

3. Fuel System Check

Test Fuel Pressure:
- Connect a fuel pressure gauge to the fuel rail and turn the ignition to the ON position (without cranking). Pressure should meet manufacturer specifications (typically around 50-60 psi).
Replace Fuel Filter if Clogged:
- If pressure is low, replace the fuel filter.
Inspect Fuel Pump Operation:
- Listen for the fuel pump's operation when the ignition is turned on. If no sound, consider replacing the fuel pump.

4. Ignition System Service

Check Spark Plugs:
- Remove spark plugs and inspect for wear or fouling. Replace if necessary with OEM or equivalent parts.
Test Ignition Coils:
- Use a multimeter to check the resistance of each ignition coil. Replace any that are out of specification.

5. Starter Motor Examination

Check Starter Connections:
- Ensure all connections to the starter motor are tight and free of corrosion.
Test Starter Functionality:
- Use a jump starter or directly connect the starter to the battery to see if it engages. Replace if it does not work.
